POTTERY-SPINNING WHEEL.

State of Ohio, have invented a certain new 'and useful Improvement inPottery-Spinning IVheels, and do hereby declare that the following is afull, clear, and exact description thereof, reference being had to theaccompanying drawings, in which Figure 1 is a side elevation o f aspinning wheel embodying my invention; F ig. 2 a vertical section on theline 2-2 of Fig. 1; Fig. 3 ahorizontal section on the line 3-3 of Fig.2,

and Fig. 4 is a detail view in side elevation of v designates a suitableframe having bearingsfor a vertical shaft 2 that at its upiper endcari-ies a spinning wheel 3, the sha t being provided with a fast pulley4 and a loose pulley 5 for alternate engagement by a belt 6 receivingmotion fromY a suitable source.

The shaft 2 is hollow or tubular, and vertically movable Within it is an'icld-lifting rod 7, which at its upper end has a head or cap 8 toengage the bottom of a mold 9 in the spinning wheel. Also mounted inbearings in the frame 1 is a rotatable and vertically reciprocable rodor shaft 10 which, at its upper lend, supports and carries a disk plate11,

having in its edge a series-as shown four' of semi-circular notches 12,each adapted to receive and support a mold, for which purpose the moldis provided at its top with an annular fiange formed by an annulargroove 13 just below the to of the mold in a rim. or fiange on the inoll t iat rests upon the upper edge of the spinning wheel, the moldbeing placed in and removed from engagement with the plate or disk-notchby a horizontal movement. of the mold. The rotation of the mold-suporting plate or disk is for the purpose of 4lbringing the molds carriedthereby successively into position in and out of alinement withthespinning wheel, and its vertical Specification of Letters Patent.Application led June 30, 1906.

` mold into the spinning wheel, and.4 then lifting it therefrom, thesemovements taking place in succession for the placing of a vessel to beoperated upon n1 the spinning wheel and removing it therefrom, and allthesein c-vements are produced automatically, as will be hereinaftermore fully described.

UNITED saires- PATENT ermee. l

The rib or former 14 which has an edffe corresponding to the interiorsurface to liev formed 'on the vessel is carried by an arm 15, to whichit is removably attached, so that ribs of different configuration may beeinployed, said arm being pivoted to a. vertically reciprocable-rod 16,so that the rib has a compound movement consisting of a verticalmovement lto project it into the vessel within the mold, and cause it toengage and operate on the interior surface thereof, and to lift the ribout of the mold, and of a swinging movement to carry it to one side ofthe vessel in the mold when it has been removed therefrom, so that itwill not hinder the lifting of the mold with the vessel therein from thespinning wheel, and to bring it again into position for action upon thevessel in the mold. To impart this compound motion to the rib, itscarrying arm at its pivoted end has attached to it a pinion 17, which onone side meshes with a stationary rack .lfastened to the frame 1, and onits op osite side meshes with a similar rack carriedl by a pit-man 19,whose lower end is pivoted. to a crank pin on a worin wheel 20, so thatby the revolution of the latter the pitman is reciprocated and its rack,meshing with the pinion, revolves the latter, thus imparting theswinging motion to the rib, and the vertical motion being produced bythe action of the pinion upon the Vstationary rack 18. Contiguous to theath of the rib or former, just before it com etes its movement away fromthe vessel in t e mold, is a plate or blade 21 conveniently made ofsheet-metal sup orted by an arm 22 from the frame I, an having an edgewhich Will engage and clear or scrape from the rib or former any claywhich may adhere thereto. To automatically shift the belt 6 from onepulley to the other, I attach to the verticall reciprocating rod-16 abelt shipper 23, whic when the rib or former descends into the vessel inthe mold, shifts the belt into engagement with the fast pulley to causethe when the rib or former is lifted from the vesmovement is for thepurposecf lowering a sel inthe mold, shifts the belt to the loose 4110'spinning wheel.

G connected to pulley to stop the revolutionofthe spinning whee so thatthe rotation ofthe spinning Wheel is automatically controlled.

The lifting of the\meld=carrying -late or disk 11 is automaticallyaccomplis ed uby means of an arm 24 attached to and projecting atright-angles from the pitmanli) and a disk or wheel 25 on tlie rod orshaft 10 which l supports said plate 'or disk, said arm beingAmold-carrying disk or plate, moves horizon- Atally into engagement witha ratchet tooth and thereby rotates the wheel and its shaft. On thedescent of the arm 24, the mold-carryino' disk or plate descendsautomatically by the action of gravity and places a mold with a newvessel to be operated on in the Simultaneously with the rising andfalling of the mold-carrying plate or disk, the mold-lifter is raised tolift the mold containing the finished vessel from the spinning wheel anddescends back into the` spinning wheel, the raising of the lifter beingaccom lished by means of an arm 27 attache to the verticallyreciprocating rod 16 in such 'a position as to engage the lower end 'ofthe lifter-rod 7 when the vertically reciprocating rod 16 is raised, andthe lifter descending by gravity as the arm 27 descends when itscarrying-rod 16 moves downward. I also mountupon the vertically movablerod 16 a horizontal arm 28, which extends in position to have contactwith the bottom of the spinning wheel to act as .a stop or brake toarrest the revolution thereof. by the time the belt is shifted from thefast to the loose ulley, thus avoiding the inco"venience W iich wouldresult from the continued revolution of the spinning wheel and mold, dueto their momentum.

vWater or other liquid, such as coal oil, should be supplied to thevessel being molded, and I provide means for automatically deliveringwater to the interior surface of the vessel being operated on. Suchmeans may have various forms. Thus I may provide a tank or receptacle 29located sufficiently above the spinning wheel so that the liquid willass therefrom through a tube or 'pipe 30 w ose discharge end is at theroper point for the deliverv of the liquid to tile vessel being molded,the water orother liquid being supplied to the vessel by a pump 31 thatis autoinaticaly operated by its' piston being the belt-shipper 23f .Apipe or' tube 32 runs from the umplto the tank or receptacle. .Ipreferab y mount the tank or receptacle on the rib-carryin' arm 15, sothat the discharge of water may be controlled by the movements of saidarm. arm is lowered or moved into )osition for operating on the vesselin the mo d, the pipe 30 will be placed in' such' osition that wateriwill constantly flow or drip from the tank 30 into said'vessel, whilewhen said arm is lifted to taks: the. 'rib out of .the vessel iii themold, the pipe 3() will be lifted to .cause the stoppage of thcilow ofwater. I also mount on the arm 15 a tool to scrape orclean the upperedge of the mold, 'which consists of a shank 8'0 33 adjustably attachedto the arm 15, and carrying a knife or blade 34 at its end to engage anyclay. adhering to the mold and scra e it olf, when the arm 15 is inposition to I a so may provide for delivering a jet of water to the ribor former after each operation of the blade 21 on it, to Wash it.

The operation of my s inning wheel is as followsz-With the mol carryingdisk or 90 plate in an elevated iositon, moldswith the vessels to beform therein are placed, one

at a time, in the notches or recesses in the -A plate or disk, and thelatter, with the mold,

directly above the spinning wheel,' descends, 95

carrying such mold into the spinning wheel, the pitman 19 descendin at te same time, and throuvh the rack an pinion mechanism describedtbringing the rib or former downward into the vessel, and also movingdownward the bar which carries the belt-shipper 23, so that by the timethe rib or former ias reached its operating position, the belt will beshifted from the oose to the fast pulley,

and the revolution of the spinning wheel with the contained mold willtake place at a rapid rate of speed. The rib oi' former having operatedon the vessel being made for the desired length of time, which isdetermined by the rat-e of revolution of the worin wheel '119 20, thepitnan will, by its upward movement through-the rack and pinionmechanism, lift the rib or former out of the vessel and swine it to oneside, and at the same time, the lbelt shifter will move the belt fromthe tight to the loose pulley, and the moldcarrying disk or plate willbe lift-ed to lift the mold containing the newly formed vesselA out ofthe spinning wheel, bein@r supplemented by the mold lifter 7, and thelifting 12g,

of the mold from the s inning wheel being accomplished, the mol carryingdisk-or plate will be revolved a quarter of a turn to remove the moldwith the newly-formed vessel from over the spinning wheel, and to "1,25bring the next mold with a vessel tobe operv ated on into position overthe Spinnin wheel, ready to be lowered therein.
